I get the joke, but for those seriously wondering:
The epoch is Jan 1, 1970. Time uses a signed integer, so you can express up to 2^31 seconds with 32 bits or 2^63 with 64 bits.
A normal year has exactly 31536000 seconds (even if it is a leap second year, as those are ignored for Unix time). 97 out of 400 years are leap years, adding an average of 0.2425 days or 20952 seconds per year, for an average of 31556952 seconds.
That gives slightly over 68 years for 32 bit time, putting us at 1970+68 = 2038. For 64 bit time, it’s 292,277,024,627 years. However, some 64 bit time formats use milliseconds, microseconds, 100 nanosecond units, or nanoseconds, giving us “only” about 292 million years, 292,277 years, 29,228 years, or 292 years. Assuming they use the same epoch, nano-time 64 bit time values will become a problem some time in 2262. Even if they use 1900, an end date in 2192 makes them a bad retirement plan for anyone currently alive.
Most importantly though, these representations are reasonably rare, so I’d expect this to be a much smaller issue, even if we haven’t managed to replace ourselves by AI by then.
If you’re going to correct people about Dune quotes, at least use one from the book! “The spice must flow” doesn’t appear in any of them, it’s a Lynch addition.
Windows, Linux, FreeBSD, OpenBSD, NetBSD, and OSX have all already switched to 64 bit time.
Tell that to the custom binary serialization formats that all the applications are using.
Edit: and the long-calcified protocols that embed it.
So they have a year 202020 bug then

I can’t wait to retire when I’m 208 years old.
Omg we are in same epoch as the butlarian crusade.
Butlerian Jihad, my dude. Hate to correct you, but the spice must flow.
Im just glad you got that reference

Yes but it’s the most accessible dune quote.
Cars haven’t. A whole lot of cars are gonna get bricked.
